eBay GPS antenna test.

It's still extremely rare to see a low-priced used triple-frequency
antenna on ebay. For less than US$300 I've only spotted extremely
beat-up Zephyr Geodetic Model 2s and a few Leica AX1203+ GNSS (only
the "+GNSS" model is triple-frequency) (there is one up right now).

I've seen at least one Zephyr 2 listing that had a picture of a
Zephyr 1 attached (look for the bigger bump in the top center on the
model 2).

I have yet to see a triple-frequency receiver for under $500....

I have gotten some deals on eBay I just couldn't have gotten elsewhere.
That is a nice looking antenna. A bit pricey for my budget. I thought just
north of $100 for a used Leica choke ring job was about it. The Trimble
antenna I got recently had issues, so I got it cheap and fixed the
mechanical problems. I think I have one of those HP timing antennas I have
heard mentioned here. I need to dig it up. I think I also have a PC Tel
model around somewhere. I still haven't gotten the top off that Chinese
made one that bit the dust at 12 volts. I need to get it apart somehow. I
think it can probably be repaired. I can at least let the seller know what
went bad.

Hi

I think you probably will have to move up to around $500 or so (and
still shop pretty hard) to find a Zephyr Geodetic 2 in excellent condition.
A Novatel 703 Pinwheel would also be on the list of things to watch for.

If you find a proper (L1 / L2 / L5 ) GNSS receiver with a pps out in working
shape for $500, go for it. They tend to be quite a bit above that price. Most
of what is in the $400 to $1000 range are L1 / L2 GPS only devices. Even
with them, finding one that will do timing is a bit tough.
